Abstract

L'invention concerne un procédé et un appareil pour la détection des attributs d'une alimentation électrique d'entrée. Le procédé comprend la réception d'un premier signal généré en fonction d'un second signal qui est prédictif. Le premier signal comprend une partie qui correspond pratiquement au second signal. En outre, le procédé comprend la détection des attributs de la partie du premier signal qui correspond pratiquement au second signal, et la détermination des attributs du second signal en fonction des attributs de la partie du premier signal qui correspond pratiquement au second signal.
